MACHINE FOR DRESSING SHIPS SIDES.

SPECIFICATION forming part of Letters Patent No. 299,639, dated June 3,1884. Application filed Octaber 20, 1883. (No model.)

To all whom it may concern.-

Be it known that I, J OHN HAMILTON, of St. Johns, New Brunswick, Dominion of Canada, have invented a new and Improved Machine for Dubbing and Planing the Sides of Vessels, of which the following is-a full, clear, and exact description.

My invention consists of a contrivance of machinery whereby a rotary cutter or planer may be applied to and operated upon the sides of vessels to dub the same, by means of a crankshaft to be operated by hand; or power may be applied, if preferred, so as to dub and plane the sides of vessels better, faster, and with less labor than by the ordinary methods of dubbing and planing by hand-tools, as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part of this specification,"

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my improved dubbing and planing machine applied to the side of the ship for use, with some parts in section; and Fig. 2 is a cross-sectional view of the machine on line :20 a", Fig. 1, looking upward, and with some of the parts in section.

I mount a beam, a, that carries the cutter and its driving-gear, in two curved and slot ted supports, 1), so as to be shifted along said supports by the blocks 0, arranged in the slots or ways of said supports, and by the screws cl, connecting the ends of said beam to said blocks,with nuts e and washers f, to bind the frame fast at any position in the supports, as thebeam is to be shifted from time to time by swinging it as on a pivot at the center between the supports 72 to set the cutting-tool or planer for successive operations. The supports 1), whichare a little less than semicircles, are connected together at the ends by the bars 9, and they have guidelugs hat said ends, by which they are fitted in the grooves of a pair of guide-timbers, 13, that are connected to the ships side j by bolts and nuts 70, with temperscrews Z between said bolts, by which the guide-timbers are adjusted parallel with the sides of the ship,'so that the planing-tool carlied on the beam at will be properly gaged to shifted up and down the side of the ship in the supports b, andwhen it is shoved along the side of the ship by moving supports 1) along the side of the ship, both when the frame is bracket, p, and said arbor being also geared by a pinion, q, with a train of driving-gears to be operated by the crank-shaft s, and said pinion q being fitted to the arbor so as to al low said arbor to be shifted through it for adjusting the cutter, as above stated. The frame a is also pivoted on the bolts (1, connecting it to the blocks 0, and is made to swing or cant, so as to be always parallel with the part of the ship operated on, by an adjusting-screw, t, or it may be a lever, said screw t being fitted in a bracket, a, of one of the blocks 0 and arranged to turn the frame more or less on the bolts (1, to adjust the tool to the surface of the vessels side to be planed;

It will be seen that the supports b will traverse the guide-timbersi when they are sprung to the curvature of the ship without binding by means of the guide-lugs h, to carry the dubbing and planing-tool along the curved sides of the ship; also, that the tool can be swung up and down the side of the ship, parallel to it, by oscillating it in the supports 1), and the tool can be set parallel to any part of the varying form of the ships side by the screw 15, and can be shifted by the adjusting-screw o to reach the surface and to regulate the cutting of the same, so that all or nearly all parts of the sides of the ship may be dressed with much less labor than in the common way. The machine is to be operated by two men, one of which will turn the crank to give motion to the outting-tool,while the other shifts the machine along the ways i and up and down the supports 6.

5 joints,when it may occur that one will have to be sprung more than another to conform with different curves of the side of the ship. This may be done by fitting bolts '0 slack in the bars g. The machine is to be used inside or outside of the ship, and is to be fitted with different forms of cutters adapted for plank or timber. A balance-wheel will be fitted in the cutter-arbor at any suitable place,to facilitate steady motion of the cutters.

Along the sides of the vessel where it is comparatively straight the guides t can be as long as may be convenient; but around the bow and under the center and run at the stern, where the curves are quicker, the length of the guides may be limited.

It is to be observed that the beam at is to be set firmly in the supports b by the screws (1 and nuts 0, while the machine is being shoved along the guides for making the out. The screws are then to be slaekened to shift the cutter up or down for another cut, and then the beam is set again until the whole space between the guides i is dressed. The guides are then shi ftcd to a new position on the side of the ship, and so on.

It is designed to construct the machine in suitable size to dress a space about three feet wide between the guides i, but of course it may be larger or smaller, as preferred.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, in a dubbing and planing machine, of a beam, a, having a cutter and driving-gear mounted on it, curved supp'orts b, in which said beam is adj ustably mounted, and guides i, attached to the ships side and having the supports 1), arranged to be shifted along them, substantially as described.

2. The beam a, having the cutter and driving-gear mounted on it, in combination with curved supports 0, arranged in the guides i, the beam to being connected to the supports 1) by the blocks 0 and bolts (1, the blocks being adjustable along the supports, and the bolts being arranged to clamp the beam fast to the supports, substantially as described.

3. The beam a, having the cutter and driving-gear mounted on it, in combination with the supports 1), arranged in guides i, the beam being connected to supports I) by clamping and pivot bolts (7, whereon the beam is adjustable to adjust the cutter to the surface of the ships side, substantially as described.

it. The beam a, having the .cutter and driving-gear mounted on it, in combination with the supports 1), arranged in the guides 1 and being pivoted on the connecting'bolts d, and having an adj listing-screw, f, to set it on said pivot-bolts, substantially as described.

5. The beam a, having the cutter and driving-gear mounted on it, in combination with the supports 1), arranged in the guides i, the eutterm being adjustable to and from the beam by an extensible arbor, to adjust it to the work and to regulate the depth of the cutting, substantially as described.

(3. The beam a, having the cutter and driw ing-gear mounted 011 it, in combination with the supports 1) and guides i, and being adjustable on its pivot-supports d, and the cutter being arranged on an extensible arbor, substantially as described.

7. The combination, with guides i, attached to the sides of the ship by bolts 7c, and temperscrews Z, for springing them to the curves of the ship, of the beam a, having a cutter and driving-gear mounted 011 it, and the supports 1) for said beam, said supports I) being connected by bars 1 and having lugs h arranged in the grooves of said guides i,substantially as described.
